By constituting like this, the hoop bag of side's side can be oppressed the blood vessel (arteriole) of the rear side of external ear and periphery thereof, and the hoop bag of the opposing party's side can be oppressed shallow side cephalic artery or its branch vessel of the face side of external ear and periphery thereof.And, like this blood pressure of external ear and periphery (further specific then is tragus and periphery thereof) thereof has been measured following reason.

That is, the blood vessel (arteriole) of well-known tragus and periphery thereof is approaching with the blood vessel in the brain, considers the blood pressure that can measure from the brain.On the one hand, at the tragus periphery, except blood vessel (arteriole), also have and the direct-connected tremulous pulse of heart (shallow side cephalic artery) with the cartilaginous part (mainly being tragus) that is present in ear.Therefore, has and to measure simultaneously with little device at the tragus periphery and have different information the advantage of the blood pressure of (promptly from the blood pressure in the brain with from the blood pressure of heart).By the photoelectricity volume pulsation sphygomanometer of present embodiment, can make the signal standards of pulse signal become the interior signal standards of specification limit that enters regulation, can carry out the high-precision blood pressure determination of external ear periphery.Simultaneously, owing to can shorten the time of measuring blood pressure, thereby can alleviate the body burden that hoop bag pressure produces user.

As described above, photoelectricity volume pulsation sphygomanometer according to present embodiment, can adjust the signal standards of pulse signal, the signal standards of pulse signal is entered in the specification limit of regulation, when can carrying out high-precision mensuration, can also shorten the time of measuring blood pressure, can provide to alleviate the photoelectricity volume pulsation sphygomanometer of hoop bag pressure the burden that health produces of user.

In addition, though above-mentioned blood pressure measurement apparatus utilizes light-emitting component 20 and photo detector 21 to detect pulse, but also can have the hoop bag to determined position compressive pressure, the pulsation that the blood vessel of organism surface is produced with this hoop bag changes as pressure catches, thereby detects pulse.

That is, will change by the pressure that the hoop bag of exerting pressure is converted in the hoop bag from the pulsation that organism obtains, the pressure that detects in the hoop bag with pressure-detecting device changes.By such structure also can the detection of biological body pulse.In addition, can also lapel mike partly be set, the korotkoff's sounds that produces when detecting, the generation of the above korotkoff's sounds of standard or disappear and measure blood pressure according to the rules with hoop bag compressing organism a part of at the hoop bag that contacts with organism.

The invention is not restricted to above-mentioned embodiment, can carry out various changes and distortion not exceeding the spirit and scope of the present invention.Therefore, in order to disclose scope of the present invention, enclose claims of the present invention.
